New research on making glass more stable could lead to the creation of stronger metals and faster-acting drugs, researchers claim. Scientists at the universities of Chicago and Wisconsin-Madison in the US say they have shown that glass manufactured on specially prepared surfaces can have the molecular stability of glass that has been aged for hundreds of years. They argue that their research on the amorphous molecular structure of this glass could aid the creation of drugs that don’t crystallise during storage and so can be delivered faster in the bloodstream, as well as the development of amorphous metals that are better at absorbing impacts.
